Chart electrical cable size in mm.

Wire gauge refers the physical size of the wire rated with a numerical designation that runs opposite to the diameter of the conductors in other words the smaller the wire gauge number the larger the wire diameter. Single phase amps three phase amps 1 5. For example 7 0 2 means 7 strands of wire each 0 2mm. These are mostly used for appliances and objects that require much more electrical power to operate or special use situations.

Common sizes include 14 12 10 8 6 and 2 gauge wire. The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient air temperature of 30 c 86 f.
